Thank you blkbird.
I was wondering when someone else was going to jump in here! I am still at a loss to understand how you can fill plate with fiber tow (which weighs the same as the fiber in fiber weave, because fiber weave is made from fiber tow) AND epoxy, and have it weigh less than a structure which is mostly air by volume.
Also, in our lab we have Nomex honeycomb ranging from under 1/8in, to over 1 in. I don't know where the 0.21 in number comes from either.
Boy angelo, you really started a thread here :surprised
Well it looks like all the original posts that started the "discussion" have been deleted, so I guess it's over...
